Those who keg wish they had done it earlier. Those that bottle think kegging would be cool but learning the system and spending the money + making a kegerator is a lot of extra time especially if you're new to the hobby.
I have a lot of local breweries like Harpoon, Hill Farmstead and others that sell kegs so my logic is that if I abandon homebrewing, I can just convert to Sankey connectors and have my favorite beer on tap!

Here's what I started with
http://www.midwestsupplies.com/brew-logic-quadruple-tap-draft-system-with-4-way-gas-manifold.html
Chose 5Pound CO2 Tank which fits in the fridge.
Switched the single CO2 regulator out for a dual regulator so I could serve Soda at a different PSI as my beer.

Then I bought some faucets for $30ish a piece and a crap load of cable + line cleaner.
Finally, I spent $350 on a full-size fridge that can hold 4 pepsi cans that already had the holes drilled in the front door...I store hops in the freezer and kegs below.
Here's my setup:

There's a kegging section on this site where guys do it much cheaper and they are experts..I'm still new at this.
Naturally, getting a dorm fridge that holds 2 kegs is much cheaper but having 4 beers on tap + 5 carboys fermenting + 2 kegs of beer ready to be tapped is a great pipeline to have...if I suffer some life altering injury, I have 55 gallons of beer ready to be on tap and serving within 24 hours of kegging it using the force carb method whereas bottling and you need at least 3 weeks from the fermentation ending to waiting on bottles to carbonate.
